VISTA 之后的网络模块都变了，貌似没有 \Device\TCP 和 \Device\UDP 了

原来的TCP设备对象，没有记错的话是由驱动tcpip.sys创建的，Vista之后微软引入了Windows Next Generation TCP/IP stack的概念，把ipv4与v6整合在一起，双栈合一，由tcpip.sys实现。

但是为了兼容原来的TDI应用，Vista之后多出了一个tdx的为了兼容的驱动，由tdx创建\device\tcp等设备。
本来tdi这个过滤层就是微软很头疼，想废弃掉的一层，tdx又是为了兼容tdi client产生的，如果一个client不去使用这些旧接口，也是可以说得过去。
楼主的具体问题不是很清楚，希望这些能帮上忙。
